Abstract

L'invention concerne un pansement à vide mécanique comprenant : une première couche de soupape comprenant une première soupape unidirectionnelle; une seconde couche de soupape comprenant une seconde soupape unidirectionnelle; la première couche de soupape étant jointe à la seconde couche de soupape de façon à définir entre elles une chambre; la première soupape unidirectionnelle étant conçue pour admettre un fluide dans la chambre par l'intermédiaire de la première soupape unidirectionnelle mais pour empêcher que le fluide ne sorte de la chambre par la première soupape unidirectionnelle; la seconde soupape unidirectionnelle étant conçue pour évacuer le fluide de la chambre par l'intermédiaire de la seconde soupape unidirectionnelle mais pour empêcher que le fluide n'entre dans la chambre par la seconde soupape unidirectionnelle; et la seconde couche de soupape comprenant un matériau élastomère de sorte que (i) lorsque la seconde couche de soupape s'éloigne de la première couche de soupape, le volume de la chambre augmente, et (ii) lorsque la seconde couche de soupape est ensuite libérée, la seconde couche de soupape retourne vers la première couche de soupape et le volume de la chambre diminue.
